SAMPLE ::
*********

Thanks for your help, kind sir. Admittedly the formula you posted was a bit hard to digest though, since we've never learned anything of the sort before (or maybe it could just be due to my own incompetency in maths).

does stpm become easier ?

Is your weight truly 50 kg? We are looking at this range of dosage:



Using the formula of sum to infinity, you can calculate the upper range (safe level) of the initial dose based on your body weight.



Similarly, from the derived formula of the concentration just before the 2nd dose, you can calculate the lower range (effective level) of the initial dose based on your body weight.



However, there is a conflict because the value of the lower range cannot be higher than the value of the upper range. Because the safe limit is of higher priority, we need to determine the concentration just before the 3rd dose:



Thus, the effective and safe dosage for every 24 hours should be at this range:

No.

But the system makes and forces you to work very hard compared to the terminal system (due to the number of workloads + assignments + projects) and that makes you study harder and therefore score better.

Exam questions have not got any easier. We did past year questions, we can tell.

but it would be better in a way that it adopts university style

Critical_Fallacy,
Thanks for clarifying us on that question 2a(i) .Yes, I've too found out that when the n approaches infinity, the result obtained from is not different from that of .

I also discussed with my classmate about the question 1(a), and I'm relieved to say that I know where my mistakes are and all my doubts have been cleared. I made an error when I failed to find out the correct equation for , which is supposed to be 50.0000( in post #106). This is the another method that I used:

When n=1,2,3,4...







When we keep on increasing the n until n=∞, the quantity of quinine that is in the body will converge to a constant of 66.6667

Dear scgoh123 and sagethesausage, do both of you happen to got your hands on any Chemistry books that are not published specifically for STPM students, yet are still capable of guiding us throughout the semester?

The reason I asked because yesterday I found a Chemistry book from my school's library which is very compact with lots of notes and information. But, I find it hard to get along with it as most of the content in it are not under the scope of STPM syllabus. But, if you're an avid reader, then why don't you give it a try and search it in your school library?

Title: Chemistry(4th Edition)
Author: John E. McMurry, Robert C. Fay

*On the side-note: The one that I have from the school is the old one, as there is the 6th Edition for it.

Another book that hooked me on is the one that my classmate has, and compared to the above book, this one seems to cover more of STPM syllabus. There are numerous interesting explanations that we can fathom if we scrutinize them and I've lot to see on what it can offer. I had only superficially went through certain sections under the Ideal Gas Law and some other part pertaining to allotropes and unit cell, but what I can say is that it will be a very good tool for those who want to elevate their knowledge of Chemistry on a whole new level and sharpens their insight about this subject.

Title: Chemistry: The Molecular Nature of Matter and Change
Author: Martin Silberberg

Most Introductory Chemistry textbooks cover more or less the same general materials. They usually differ in the way the authors organize the materials to help students developing a solid understanding and good command of the fundamentals of molecular chemistry. Search for this book in your library. Please inform maximR as well. Because Chemistry and Physics are the two major branches of science that study matter, many physicists also acquire a good command of general chemistry.

Chemistry: A Molecular Approach, 3/e (2014) by Nivaldo J. Tro

Thanks for your recommendation. I've searched in my school's library but there isn't any book that matches with it. I will try to get it via the e-book if I'm able to.

There could hardly be any chance that most of the Form 6 students to get their hands on these books nowadays as they are specifically made for the terminal system, but since I was able to find 2 decent Chemistry books that are beyond the STPM level in my library, I think everyone should give it a try nonetheless.

Title:Federal Topical Tutorial(Physics)
Author(s):Lam Chok Sang, Lim Seang Kee

For Physics, I'm using this book as a tool for my revision. I have not complete much of the exercises yet, but according to one of my classmates, he has a steadfast progress in doing most of the exercises in that book and he told me that even the first few topics of those exercises are making him 'nuts'. Apparently, the authors for the book are Lam Chok Sang and Lim Seang Kee, and both of them too are the authors for the Longman (Physics Term 1). The questions in the book(Federal Topical Tutorial(Physics)) are extremely challenging, and that was why I decided to only try them out after I truly understand the concept of each single chapter.

Title:Federal Topical Tutorial(Physical Chemistry)
Author: Krishnasamy Samynathan

I would say this is the best book for the subject Chemistry, right after Longman(Chemistry Term 1). For me, while Longman has the best explanations and in-depth notes for the subject, the Federal has the best exercises and questions.

For chemistry, I used Collins Advanced Science - Chemistry

For physics, I used College Physics – Paperback (2012) by Alan Giambattista. McGraw Hill Higher Education 4th Revised edition

I don't know for chemistry, am I having the same book with you?

I use the Longman book for notes too, way more informative than the Ace Ahead book that was set as our textbook. I wonder why the teachers want us to use an inferior book as our textbook though. For exercises I just rely on my tuition teacher cause he covers all chapters very well. Maybe I find those books to read after sem 1 stpm during the holidays when I'm free.

It's because Oxford is a more reputable publisher than Pearson Longman. It's true, because that's how majority thinks. My friends also preferred Oxford books because the publisher is more famous. To me, I chose authors over publisher, and Longman Physics for first term is indeed good. Second and third are not good enough (for Physics).

Is Federal a publisher or collection a series of books? I'm pretty sure I have not come across with this book in bookshops or even my teachers

Nope, the author for yours is different than that of mine albeit the fact that both of them are published under Federal. I wonder why Federal Publication has stopped publishing their books? Most of them are good in quality and I even have one Further Maths book (first published in 1989) that is very old. It was given to me by my Form 5 Add Math teacher.

Mainly because our teachers want to standardize all of our learning medium during in the class. Besides, teacher will mostly give some examples or even questions from the textbook as homework and it will be really difficult to deal with if the book that the teacher is using is different from the students'.

It was a publishing company.

Like I've said in my previous post about both of the Federal books(Physics and Chemistry), they have stopped publishing books under Federal some time ago. So, it wasn't shocking at all if you haven't even stumble across one at anywhere or form anyone.

I think it's because of the decline in students who are taking STPM, or lack of experienced authors to revise or republish the book, or the implementation of the new semester system

So, how are your preparations for STPM first term going? Oh, and do you have fun time in learning Physics Chapter 6: Gravitation?

If my memory serves me correctly, you also told me that you had your trials in last month(July) right? How was it?
